This chapter series covered Amazon Neptune end to end, from foundational graph database concepts through production-grade operational patterns. It began by distinguishing property graph and RDF models, then moved into cluster architecture, query language selection, workload design, analytical processing, machine learning integration, and expert-level operational topics.
Graph models and core elements
Property graphs store data as vertices connected by edges, both carrying labels and key-value properties. This structure enables efficient multi-hop traversals for use cases like fraud ring detection and social network analysis. Queries use Gremlin (imperative traversal) or openCypher (declarative pattern matching).
RDF represents data as subject-predicate-object triples identified by URIs, enabling semantic reasoning and ontology-based inference. SPARQL is the query language for RDF workloads. A single Neptune cluster operates in either property graph mode or RDF mode but not both simultaneously against the same dataset.
When to choose Neptune over alternatives
Neptune is the correct choice when workloads involve multi-hop traversals, circular pattern detection, connectivity scoring, or relationship-first access patterns. RDS ...
